DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 701,179, dated May 27, 1902.

r Application filed March 22,1902. Serial No. 99,516. (No model.)

T (tZZ whom it may concern.-

Be it known that I, WILLIAM C. DYSART, a citizen ofthe United States,residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is a specification.

This invention relates todraft-equalizers; and the object of the invention is to provide a draft evener or equalizer of novel and peculiar construction for various oultivators, and particularly for disk plows.

A further object of the invention is to provide an equalizer for disk plows of such arrangement that three to six horses may be used and to take off all the side draft-in a disk plow regardless of the number of horses employed.

A further object of this invention is to provide a peculiar bracket adj ustably secured to a plow-axle and in which an equalizing-bar is adjustably pivoted, so that the latter may be positioned accordingto the conditions of the land by a transverse adjustment of the bracket without changing the pivot-point of the equalizer-bar.

A still further object of the invention is to provide an unequally-divided two-part draftlever connectedto an equalizing-bar secured to the plow-axle, the lever parts being pivoted together and to a plow-beam, so that the draft will be exercised entirely upon the equalizer-bar.

In the accompanying drawings, forming part of this application, Figure l is a top view, partly broken away, with the device arranged for four horses, showing in dotted lines the device arranged for three horses and five horses, with the furrow also in dotted lines. Fig. 2 is a perspective view of the several equalizing levers. Fig. 3-is a perspective View of the shaft bracket. Fig. at is a detail longitudinalsection of the draft-bar and its brace.

The same-numeral references denote the same parts throughout the several views of the drawings.

The running-gear of the disk plow, only part of which is shown, is of ordinary construction, having the usual furrow-wheel 1, beam or beams 2, and shaft 3. A triangular bracket 4 is adj ustably secured to the shaft 3 by means of a plate 5 and suitable bolts (3, which are not passed through the shaft, but above and below it, so that the bracket may be applied to shafts of various sizes and adjusted transversely thereon, according to the character of the land under cultivation-that is, if the land is tough and hard the bracket is secured on the shaft near the furrow-wheel, and when the land is in better conditionfor cultivation the bracket is adjusted on the shaftinwardly from the Wheel. This adj ust ment assists in equalizingthe draft.

The draft-equalizing bar 7 has a straight portion and a rearwardly-projecting portion at an angle to the straight portion, the latter having a series of pivot-holes 8, by means of which and a bolt 9 the said bar is pivotally adjusted in a slot 10 of the bracket 4, so that its pivotal points may be varied according to the number of horses employed or the char actor of equalization desired. To the straight portion of the bar 7 is pivoted at 11 one end of a lever 12, having diverging arms 13, and the angle portion of the said bar has pivoted to it at 15 one end of a lever 16, having diverging arms 17. To and between the arms 13 is pivoted the short portion 18 of the twopart draft-lever and a doubletree '19. The long portion '20 of the said lever is pivoted with a doubletree 21 to and between the arms 17, the said lever portions being pivoted together and to the plow-beam by a king-bolt 22, the long lever portion being stifiened by a brace-bar 23, and the short lever portion is provided with a hook or clevis 24 for connecting an additional doubletree 25. By dividing the draft-lever into two unequal parts and pivoting them together and to the plowframe the draft is made on the equalizingbar 7 and not at the front of the plow-beam, as in the ordinary manner.

The advantage of the adjustable bracket at and the two-part lever having been stated and the reasons'and objects of the various pivotal adjustments'of the equalizing-bar 7 having been described, it is obvious in working three horses a singletree is substituted for the doubletree on the long portion of the two-part lever, and the bar 7 is changed to one of its pivot-holes. WVith the device in this condition two additional horses may be;

used by employing the doubletree 25. When six horses are to be used, (four in the rear and two in front,) the device remains the same as described for three horses, except the doubletree is replaced on the long portion of the two-part lever. It is obvious that the device may be attached to a plow frame or beam by other means equivalent to the bracket. It will be seen thata double equalization is effected regardless of the number of horses employed or the position of the bracket on the plow-shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- Y 1. A draft-equalizer com prising an adjustable bracket, a two-part equalizing-lever anchored pivotally together, an equalizing-bar pivoted to the bracket and having a straight portion provided with a series of pivot-holes and a rearwardly-projecting portion, and the levers pivotally connecting the outer ends of the two-part lever with the said bar.

2. In a draft-equalizer the combination, with the bracket adapted to be adjustably connected to a cultivator-wheel axle, and the two-part equalizing-lever pivoted together and to the cultivatorbeam, of an equalizingbar pivoted in the bracket, and the levers connecting the said bar with the two-part lever;

.3. In a draft-equalizer the combination, with the triangular bracket having a slot, and the equalizing-bar pivotally adjustable in said slot, of the two-part equalizing-lever, and the levers having diverging arms and connecting the two-part lever with the said bar.

4:. The combination, with a disk plow, of
